Well, it depends.

When correcting, always start with the least aggressive pad and compound (can use even polish) on a small area to see what works. However, BMW paint is pretty hard. For example, using a DA orbital with a white lake country (very light cut) foam pad and wolfgang's total swirl remover 3.0 is not a bad starting point. If that doesn't remove the swirls and light scratches, step it up with wolfgang and a medium cut pad such as an orange lake country pad. Remember, technique is very important too.

You can go even stronger using a compound like Meguiars M105 with the same pad or a pad with more cut (i.e. yellow lake country) for deeper scratches. But remember, if you go that strong, you will be taking a good amount of clear coat and will need to go over the same area with polish to remove the fine scratches and marring the compound and cut pads left behind. I don't recommend it. Go about that step at your own risk or find a good detailer.

To be safe, make several passes (4-6) before stepping up. The great thing about all the equipment available is that you can adjust your approach according to the condition of the paint, making your job easier. But being able to determine that comes with experience. Hope that helps.
Thanks, very helpful info here.
